rings of minute perichaetine setae; in the most anterior segments of all they are smaller 
than in the rest of the segments in which they occur. They may possibly represent 
sensory papillae (cf. Drawida ghatensis, ant.). 
No clitellum was distinguishable. 
The male pores appear as slitsin furrow 10/11, marked only by a slight thickening 
and whitening of the intersegmental furrow at the junction of the lateral and ventral 
areas of the body-wall, i.e. between bandc. No other apertures or genital marks were 
visible. 
The nephridiopores are some in the line ab, others in cd; but there is no regular 
alternation. LA 
Internal anatomy.—The anterior septa have the exact relations described in the 
case of the preceding form ; septa 5/6—8/0 are much thickened. 
The gizzards are four in number, in segments xv—xviii ; they are spherical or 
somewhat flattened antero-posteriorly, are all about the same size, and are preceded 
by a firm portion of the oesophagus in xiv. 
The testis-sacs are ovoid, attached to septum 9/10, projecting backwards into 
segment x but not forwards into ix. The vas deferens consists of large bunches of 
loops, in both ix and x, which are prominent and look at first sightlike a bushy gland, 
anovaryforexample. Theloops are all attached to the septum, or to the base of the 
testis-sac where it joins the septum, and cannot be seen to communicate with one 
another at their attached ends. The vas emerges from the tangle near the body- 
wall in x, passes back to the prostate to which it applies itself near its ectal end, 
ascends along the inner face of the prostate, bound down to the latter by connective 
tissue, and enters the substance of the prostate at its posterior (ental) end. 
The prostate, attached to the body-wall in the situation of 10/11, is narrow at 
its origin, rather twisted, firm and indistinctly shiny,—hence probably muscular. 
The organ passes back as far as segment xiii, becoming much broader, and with its 
fellow entirely covering the dorsal aspect of the gut. Segment xiii is bulged both 
forwards and backwards by the swollen and curved posterior ends of the glands, 
these posterior ends, as said above, being joined by the vasa deferentia. The glands 
are of an opaque white colour, their surface is marked out by shallow depressions 
into slightly marked lobes, but is otherwise smooth. The organs are bulky, and 
with the gizzards are the most conspicuous objects on opening the worm. 
Though the male apparatus and, as will be seen, the spermathecal apparatus 
were quite fully developed, I could find but little trace of the female organs. 
Ovaries and egg-sacs were absent; there appears to be an ovarian chamber, as in the 
previous species and in Dvawida; rudiments of the female funnels were identified, 
though somewhat doubtfully. 
The spermathecal ampulla is in segment viii, attached, as usual, to the posterior 
face of 7/8 and overarched by the nephridium ; it is of ovoid shape, and is continued 
into a narrow duct, the coils of which project backwards into segment viü. The 
duct penetrates septum 7/8 near the body-wall, and, having become more transparent 
and difficult to follow, it joins the atrial gland on its upper border. The atrial
